You are a mercenary.
* Loyalty does not exist (company, coworkers, etc)
* You dictate pay for the work you do (or leave the job)
* You dictate your own hours (overtime is your own choice not company's)
* Strive to always provide maximum value (efficiency not time spent)
* Focus on keeping a core set of skills sharp
* Quit if conditions are untenable
When a person does the above, they start focusing on how to provide value instead of "doing a job". A person can be a phenomenal engineer and yet have a poor career because they never figured out how to be a valuable engineer.
